Lets Encrypt certificate expiration

Hi all,

I use LE and Im so far happy, I have following scenario:

  • Website use https
  • But when I renew the certificate I have to open port 80 on my server and renew that and close it again, its possible to renew the certificate through port 443 or better way?

thanks in advance

Hi @neeloj

that’s the wrong way having a public visible domain name and a webserver.

Please read

If you want to have a working webserver, port 80 must be open. If you think that’s a security problem - that’s wrong.



Okay thank you very much (Vielen Dank) @JuergenAuer, I’ll read both articles and give my feedback here to others too…
